[ad_1] what did you try so far? there is no problem in having the table name coming from a DropDown, it’s more about understanding and designing the Data Access layer for your application. Do you have a save button in your WebForm and are you composing the SQL code dynamically in the code behind or … Read more
[ad_1] A delegate is basically a method pointer. It has a reference to the method, and its object (unless it’s a static method, of course). You use a delegate whenever you need to call a method but the code calling it doesn’t know which method it is. The most common reason is that the code … Read more
[ad_1] Finally, I found solution to this. When I install Entity Framework, EF places some default code in application’s config file. As below: Problem Code: <defaultConnectionFactory type=”System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework”> <parameters> <parameter value=”mssqllocaldb” /> </parameters> </defaultConnectionFactory> Solution: This was root of the problem I was facing. By default it was creating a local connection string for itself. … Read more
[ad_1] Sorry, but I didn’t find a design simpler than that. You could, make a class that owns both a thread, and a weak_ptr to itself, to be a “holder” that the callable can see it safely, because the callable will still exists even if the object is destructed. You don’t want a dangling pointer. … Read more
[ad_1] #include <stdio.h> #define MAX 1000 int main() { char binarynum[MAX], hexa[MAX]; long int i = 0,number_of_zeros=0,number_of_ones=0; printf(“Enter the value for hexadecimal “); scanf(“%s”, hexa); printf(“\n Equivalent binary value: “); while(hexa[i]) { switch (hexa[i]) { case ‘0’: printf(“0000”); number_of_zeros +=4; break; case ‘1’: printf(“0001”); number_of_zeros +=3; number_of_ones +=1; break; case ‘2’: printf(“0010”); number_of_zeros +=3; number_of_ones … Read more
[ad_1] Why is reader null? It shouldn’t be. It may have .HasRows == false, but there should be an object. Why do you think it ever is null? OK, new title with a clue. You have to drop the @ in the SQL text as it denotes @UserID as a parameter and not as a … Read more
[ad_1] The top sample in this article, Accessing Attributes in the DOM, shows how to retrieve the attributes and their values for an XML snippet containing only one Element. If you combine that with the ChildNodes property of the XmlElement class, you could iterate first through all the elements and then through all the attributes … Read more
[ad_1] If you check CompilerResults compres it shows that there’s an exception and the compilation was not successful and hence it’s not writing out Assembly.exe and there is a System.IO.FileNotFound exception from Process.Start() Try this public void compile() { CSharpCodeProvider myCodeProvider = new CSharpCodeProvider(); ICodeCompiler myCodeCompiler = myCodeProvider.CreateCompiler(); string myAssemblyName = @”Assembly.exe”; CompilerParameters myCompilerParameters = … Read more
[ad_1] What you’re looking for is await <TYPE>Context.BeginDialogAsync(nameof(<YOURDIALOGNAME>), <OPTIONAL_PARAMETERS>, cancellation token The <TYPE> above means you could be using waterfalls, in which case it would be stepContext or a simple dialog, which would be dialogContext. so for your bot above, you’d create the PurchaseOrderDialog.cs and SKUNumberDialog.cs, then utilize them as follows: if (entry) { JToken … Read more
[ad_1] Dotnet core support var s = “some html / html form”; HttpContext.Response.WriteAsync(s.ToString()); Find refrence : https://gist.github.com/priore/7163408 Is there an equivalent to “HttpContext.Response.Write” in Asp.Net Core 2? [ad_2] solved How to submit http form using C# in DOTNET CORE [closed]
[ad_1] How is value getting retained even after function completing execution? Undefined behavior (UB). It might appear to “work”, but that is not specified to be so by C. fun(&ptr); runs fine, yet printf(“%p”,ptr); is UB as the value ptr is no longer valid. Many systems will tolerate this UB. De-referencing ptr, with printf(“%d\n”,*ptr); is … Read more
[ad_1] I think you need 2 structs. An astronaut and a mission aren’t the same thing. As it is now, you have several unused fields depending on whether you’re entering data for an astronaut or a mission. You could do something like this: #include <stdio.h> #define maxName 50 #define maxNation 50 #define maxAge 100 struct … Read more
[ad_1] I hope that this explanations can give you some hints. By analyzing the code functions you should be able to figure out the rest. VGA_WIDTH – width of the screen; VGA_HEIGHT – height of the screen x – horizontal position of the character on the screen y – vertical position of the character on … Read more
[ad_1] According to your list the Color rotates in a 10 years cycle and then has always 2 subsequent years with same color. Given that rule you can calculate an index in a field of year colors. #include <vector> #include <string> #include <iostream> using namespace std; int main() { const int base_year = 1984; vector<string> … Read more
[ad_1] Looking at the documentation, DownloadFile() is synchronous, so there is no callback needed. Try instead just: using (var client = new WebClient()) { client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(DownloadFileCompleted); client.DownloadFile(“https://www.apachelounge.com/download/VC15/binaries/httpd-2.4.29-Win64-VC15.zip”, “web/data/main/web.zip”); ZipFile.ExtractToDirectory(“web/data/main/web.zip”, “web/”); } This should suffice.
